Question

What number comes next in this sequence: 12 13 15 17 111 113 117 119 123 ==?==

Answer 1

12 13 15 17 111 113 117 119 123 ?

If you clearly see the numbers, these are the first prime number starting series. 2, 3, 45, 7, 11, 13, 17, 19, 23 and it will be followed by 29.

The only difference is that each number has a precedent of 1 and hence 29 will also have an addition 1 making it 129.
